I' m in market for 430 xii.is it good idea to buy now or wait for new to come.
I also have a 430EXII - as a second flash to my 580EXII.
To be honest, i can make do with it on quite a few occasions. For the price, and simplicity - go for it.
It's smaller and lighter than a 580EXII - hence it pops in my bag more frequently, and the batteries last a bit longer.
